REGISTERING INSTRUMENT.

Application led .Tuly 9. 1917.

To all whom it may concern.'

Be it known thatI, ALBERT H. PERRY, a subject of the King of Grreat Britain, residing at Hartshorn, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Registering Instruments, of which' the following is a specification.

This invention has relation to registering instruments and has for an ob] ect to provide a device adapted to be 'associated With a cream separator whereby the number of revolutions of the crank may be indicated per unit time.

Another object of the invention is to provide a registering instrument of the character above stated embodying means for'indicating the passage of Ia period 0f time, and

-means opera-ble at each revolution of the crank shaft of the cream separator to register the revolution and to total the number of revolutions during the passage of the aforesaid period of time. Y

A still further object of the invention is to provide a device of` this character adaptedito be automatically reset to initial position subsequent to the expiration of a definite period of time whereby the number of revolutions of the crank may be again indicated without arresting operation of the cream separator' oradJustment of the device.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the parts to be hereinafter more fully described and particularlyr set forth in the 'appended claims. v p

Y 13 which extends without the casing and is provided with a finger engaging head 14 whereby the sleeve'may be rotated. The sleeve 13 carries thereupon interiorly of the casing a ratchet wheel 15 to one face of which one end of a coil spring 16 is connected as indicated at 17, the opposite, or inner end of said spring being connected to the shaft 12. Said timing shaft 12 is also provided with a pinion 18 which meshes with a relatively small pinion mounted upon a shaft 19 journaled in bearings formed in an extension 2O of the frame 11. The shaft 19 also carries an escapement wheel 21 which operates in connection with an escapement lever 22 mounted for oscillation about a point 22, the opposite end of the lever being adapted to rotate in alternate directions a balance wheel 23 pivotally supported by a frame arm 24. The balance wheel is provided with the usual hair spring, and itV will be apparent that under the tension of the vspring 16, the shaft 12 andpinion 18 are rotated, the rate of rotation being controlled through the escaping mechanism the rate being preferably one revolution of the shaft 12 per minute. The shaft 12 is extended through the face plate ofthe casing and is provided with a hand 25 which rotates over the face and indicates the divisions of time upon a'circular scale 26. The spring 16 is wound through the medium of the finger engaging head 14 and the spring is held under tension through the medium of a pawl 27 mounted upon the bottom of the casing and mentioned above and likewise journaled in the back plate of the casing. The pinion 28 'is however keyed to the shaft 29 whereby it 'may rotate therewith. A spiral spring 31 encircles the sha-ft 29, with the inner end of the spring connected thereto, and the opposite end connected, as indicated at 32, to one face of Ya ratchet wheel 33 which is fiXedly secured to the sleeve 30. By rotating' the sleeves 13 and 30 the springs 16 and 31 may be placed slightly under strain before operation ofthe device, the springs being placed further under strain during operation. A pawl 34 pivoted upon the back plateof the casing serves to prevent rotation of the ratchet wheelin one'direction. The upper face ofthe pinion 28V carries a-clutch ele- Y ment 35v which is complemental to a clutch element 36 mounted upon 'a resettino device 37 which comprises ay plurality of. radial armsV 38, said device being loosely mounted upon the shaft for rotation relative thereto.

A coil spring 38 encircles the clutch element 35 and 36 and serves to retainthe clutch 'ele- Y ment injseparated relation by urging the Y ing movement of the resetting device 37 being limited by the provision of acollar 37' device 37 said shaft 41 also carrying anVv armV pinion 28 toward a lowermost position,slid

on the shaft. The face of the pinion 28 opposite that carryingthe clutcli'element 35 is 25v provided with a pin 39 which is located adj acent the periphery thereof vfor coaction with a cam element 40 mounted 'upon the corresponding side of the pinion 18 andadjacent theperiphery thereof for engagement with the p-in 39 when'said-pin and cam elements are brought togetherduring rotation of the pinions carrying the same.

`A shaft 41'is journaled at its opposite ends inthe frame 11 and back plate of the casing, and has fixed thereto a ratchet wheel 42 which 'islocated in the plane of the resetting 43 of resilient materialwhich is Xedfor rotation therewith. Apawl 44' mounted upon 40:/-

VVgatf'jrethey periphery of the ratchet-wheel 42 to prevent rotationthereof in one direction. fAnactuating pawl 45 isY mounted'foroscilla a relatively stationary point is adaptedV toention upon a fulcrum 46 and is provided VVwith a; dog 47 pivotally connected to the outer-end of thepawl, said dog bieingspring held and adapted for engagement with the periphery of the ratchet wheel'42. VA coil spring 48,

Vconnected to the pawl 45 and at its opposite end to Ya relatively stationary point, serves to normally, V:retain the pawl 45 in an initial position, and to return the pawl tos'uch, position subsequent t0 oscillation thereof to an yactuating position. An actuating rod 49- is `extended intothe casing with its outer end Vprojecting therefrom and provided with a `button 5.0, 'and its inner end pivotallyronnected as indicated at 51, to the pawl145. A rod49 is mounted for aXial movement adj acent the rod 49 Vand is disposed parallel `thereto' and provided at an intermediate portion with an elongated slot which receives a pin 46 mounted in the pawl'45. The'inner isadapted'to4 engage the teeth of the central end-of the rod' 49 carries Va pawl 45 which wheel 18. The opposite endof the rod 49 is provided with a button 50" which extends beyond the edge of the casing and is located beneath the. button 50 so as to be engaged by said button when the same ispressed inward. in a manner which will be presently shaft '5,2 with its inner end .connected to the shaft and its outer end connected Vas at 54 to a yrelatively stationary point.: lA vpawl 55 is pivotally mounted as `at 56 to a relatively stationary point for .engagement` with the periphery of the ratchet 53,'said pawl having an armV 56V which is disposedfin'the path of movement of the radial arms 38 ofthe resettingvv device.v The :upper face `of the ratchet wheel 53 is also provided adjacent its periphery with ten uniformly and cirlcumferentially spaced pins x57 said pins bev ing adapted to be struck one at-a time by' the arm 43 which as mentionedabove, is carried Vby the shaft 41. It will vbe noted from Fig 1-of the drawings, that theshafts 41 Y andV 52 extend'through the front face of the.

ment toa cream separator is setforth inEig. -4 of the. drawings,whereinit.will be noted that 60 indicates the standard and 701the Vcrank shaft which actuatesl the separating mechanism in a manner wellf known in' this e 71,'said bolt being surroundedby -afsleeve 7 3, Y rc tatable relatively, to the bolt. V:Anarm 74' art. '1 hecrank shaft 'is provided withan operating crank which includes a radial'arm 71having av handle portion which; comprises Y a bolt 72 secured to the extremity of thearm is secured atone [end to .the sleeve, andthe instrument is afiixedf to the opposite end of said arm 74. The arm 71 Yis furthermore provided with a lug V75` which4 `is'fadapted to vbe engaged by the button 50 ofthe instru-2 ment. Thus'it will be'seen that-*ifthe portion 73 of the handle is firmly grasped and vheld.- -and thecrank rotated, the button 50 of the" instrument willbeuengag'ed by thelugV 75 once during every revolution of theV crank.

and'eonsequently 'of the crank shaftV 70.

The lirstengagementcf the button 50 wjill Yalso move the rod' 49 axially, whereby the .pawl 45 Fwill .be di sengag'ed- Vfrom the central wheel 18 to permit operation.ofthe-timing mechanism( At] each `engagement -o'f the button50, the rod 49 will be moved longitudinally whereby to oscillate the pawl 45 which in turn rot-ates the ratchet wheel 47 partially, preferably one-tent-h of a revolution for each engagement of the button 50. The hand 58 on the face of the instrument will thus be intermittently moved around the graduation circle adjacent thereto to indicate successive engagements of the button 50, the scale being graduated from zero to nine, a complete revolution ofthe hand 58 thereby indicating ten revolutions of the crank shaft. During rotation of the ratchet 42, the arm 43 is moved around the shaft 41, and the free extremity of the arm engages one of the pins 57 of the ratchet 53 at each complete revolution of the shaft 41. The

result therefore will be to rotate the'ratchet 53 one-tenth of a revolution after each completev revolution of the ratchet 42. The

hand 59 on the face of the disk therefore serves to indicate tens and the hand 58 units. In View of this, where the hand 25 completes its circumscribed path about the face of the dial scale 26, the number of revolutions of the crank shaft will be indicated by observing the position of the hands 58 and 59 relative to the graduations adjacent thereto.

Just prior to the completion of a revolution of the central timing shaft 12 and consequently the hand 25 carried thereby, the cam member 40 engages the pin 39 of the pinion 28 which pin will be at that time located in a position to be engaged by the cam member, owing to the fact that the pinions 18 Yand 28y rotate in unison. The pinion 28 will'be shifted upon its shaft so as to bring the clutch members 35 and 36 into engagement, and to disengage the pinion 28 from the pinion 18. It will be noted that the diameter of the pinion 28 is exactly onehalf the diameter of the pinion 18 thereby insuring the engagement of the cam 40 with the pin 39 at each complete revolution of t-he shaft 12. The spring 31 of the shaft 29 being under tension, serves to rotate said shaft 29 in a direction reverse fromv its direc-tion of rotation during rot-ation of the center pinion 18, thereby carrying the resetting device 37 around with the pinion 28. The arms 38 will thus be rapidly rotated and upon engaging the |periphery of the disk 42 will rotate the same until the arm 43 movable with said disk 42, engages a stop pin 76 stationarily mounted relative to the casing. Rotation of the arms 3.8 of the resetting device will also serve to engage the arm 56 of the pawl 55 whereby to release said pawl from engagement with the disk 53, which disk will be rotated and the hand 59 carried by the shaft 52, returned to zero, the motion of the shaft being arrested through the provision of a radial arm 77 carried by the shaft which engages a pin 78 stationarily mounted relative to the casing. It is to be noted in this connection that rotation of the disk 53 intermittent-ly through engagement of the ypins thereof by the arm 43, will serve to place the spring which encircles said shaft, under tension, the tension being released subsequent to disengagement of the pawl 55 as mentioned above. Thus, by the time the hand 25 reaches the zero point on the dial, the hands 58 and 59 will have been returned to Zero, and a subsequent registering of the number of revolutions of the crank shaft may be begun immediately. Owing to the fact that the instrument is held upon the handle portion 73, which is grasped as stated above, the face of the instrument may be constantly observed and the rotation of the crank shaft produced uniformly thereby producing a uniform product of the cream separator. This device may be applied to any type of cream separator, and if desired may be secured to a stationary portion of the cream separator and the button 50 engaged by a lug on the crank handle instead of the arrangement disclosed.

The operation of the device may be'briefly stated as follows: During rotation of the crank shaft of the cream separator the button 50 of the registering device will be struck at each revolution of the crank shaft and moved inwardly and radially. At the first engagement of the button 50 the bu-tton 50 will also be moved inward thereby disengaging the pawl 45 from the pinion 18, said pawl being held in disengaged position by means of the spring finger 49. At each inward movement of the button 50 the ratchet wheel 42 will be partially rotated thereby carrying around the spring "arm 43. Just prior to the completion of one revolution of the ratchet wheel 42, one of the pins 57 of the wheel 52 is engaged by the arm 43 thereby rotating the ratchet wheel 52 through one-tenth of a revolution. The pinion 18 having been released in the manner above s t'ated, the detensioning of the spring 16 will carry said pinion 18 around in a clockwise direction, its rate of movement being limited by the escapement mechanism shown, so as to carry aroimd the hand 25 causing said hand to make a complete revolution in one minute. Pinion 28 being in meshing engagement with the pinion 18 the spring 31 is placed under tension through rotation of the pinion 18. Just prior to a completion of one revolution of the pinion 18 the cam 40 carried thereby engages the pin 39 thereby shifting the pinion 28 along its shaft so as to engage the clutch members 35 and 36 and to disengage the pinion 28 from pinion 18. The pinion 28 and the resetting device 37 are thus free to rotate under the detensioning movement of the spring 31, and as a result the arms 38 engage the periphery of the ratchet wheel 42 to reset or return the said ratchet wheel to normal or starting position, return movement of said ratchetwheel being limited by engagement of the spring arm 43 with the stop pin 76, The'arms 38 will also engage the Vpawl 55 to release the wheel 53 which is returned tostarting vposition by detensioning of the spiral spring associated therewith. It lwill be noted that AI-realize that iii-practice various alterations thereover may be mlade, andI therefore desire to reserve the right and privilege of changing the form oi" the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims. v

I-llaving'thus described my invention what I claim as new and desire to secure by Letters Patent is tl. In a registering instrument, a counting mechanism, means for actuating the same, aV time indicating mechanism including a ,pinion adapted to complete one revolution during the passage of one second of time,
